Investigation of Anti‐IgG Antibody Responses to the 17‐kDa Outer Membrane Protein of Rickettsia japonica in Individuals From a High‐Risk Area for Japanese Spotted Fever

Experimental Dermatology, Volume 34, Issue 7, July 2025.
ABSTRACT This study evaluated the seroprevalence and persistence of IgG antibodies against Rickettsia japonica's outer membrane protein (Omp) using a recombinant 17‐kDa antigen and Western blot analysis in residents of Minamiise, Japan—a high‐incidence Japanese spotted fever (JSF) area—and in individuals from non‐endemic regions.

Legionella pneumophila modulates the host cytoskeleton by an effector of transglutaminase activity

mLife, Volume 4, Issue 3, Page 232-248, June 2025.
Abstract The bacterial pathogen Legionella pneumophila delivers more than 330 effector proteins into host cells through its Dot/Icm type IV secretion system (T4SS) to facilitate its intracellular replication. A number of these effectors modulate organelle trafficking pathways to create a membrane‐bound niche called the Legionella‐containing vacuole ...
